Preparing your garage door
Before you begin:
• Disable locks.
• Remove any ropes connected to garage door.
• Complete the following test to make sure your garage
door is balanced and is not sticking or binding:
1. Lift the door about halfway as shown. Release the
door. If balanced, it should stay in place, supported
entirely by its springs.
2. Raise and lower the door to see if there is any
binding or sticking.
If your door binds, sticks, or is out of balance, call a
trained door systems technician.
Sectional Door
To prevent possible SERIOUS INJURY or DEATH:
• ALWAYS call a trained door systems technician if
garage door binds, sticks or is out of balance. An
unbalanced garage door may NOT reverse when
required.
• NEVER try to loosen, move or adjust garage door,
door springs, cables, pulleys, brackets or their
hardware, ALL of which are under EXTREME tension.
• Disable ALL locks and remove ALL ropes connected
to garage door BEFORE installing and operating
garage door opener to avoid entanglement.
To prevent damage to garage door and opener:
• ALWAYS disable locks BEFORE installing and
operating the opener.
• ONLY operate garage door opener at 120V, 60 Hz to

Planning
Identify the type and height of your garage door. Survey
your garage area to see if any of the conditions below
apply to your installation. Additional materials may be
required. You may fi nd it helpful to refer back to this page
and the accompanying illustrations as you proceed with
the installation of your opener.
Depending on your requirements, there are several
installation steps which may call for materials or hardware
not included in the carton.
• Installation Step 1 – Look at the wall or ceiling above
the garage door. The header bracket must be securely
fastened to structural supports.
• Installation Step 5 – Do you have a fi nished ceiling in
your garage? If so, a support bracket and additional
fastening hardware may be required.
• Installation Step 10 – Depending upon garage
construction, extension brackets or wood blocks may
be needed to install sensors.
• Installation Step 10 – Alternate fl oor mounting of
the safety reversing sensor will require hardware not
provided.
• Do you have an access door in addition to the garage
door? If not, Model 1702LM Outside Quick Release is
required. See Accessories page.
• Look at the garage door where it meets the fl oor. Any
gap between the fl oor and the bottom of the door must
not exceed 1/4" (6 mm). Otherwise, the safety reversal
system may not work properly. See Adjustment Step 3.
Floor or door should be repaired.
SECTIONAL DOOR INSTALLATIONS
• Do you have a steel, aluminum, fi berglass or glass
panel door? If so, horizontal and vertical reinforce ment
is required (Installation Step 11).
• The opener should be installed above the center of the
door. If there is a torsion spring or center bearing plate
in the way of the header bracket, it may be installed
within 4 feet (1.22 m) to the left or right of the door
center. See Installation Steps 1 and 11.
• If your door is more than 7 feet (2.13 m) high, see rail
extension kits listed on Accessories page.
SECTIONAL DOOR INSTALLATION
Horizontal and vertical reinforcement
is needed for lightweight garage
doors (fi berglass, steel, aluminum,
door with glass panels, etc.).

information relating to sectional doors in Installation
Step 11.
• Depending on your door’s construction, you may need
additional mounting hardware for the door bracket
(Step 11).
Without a properly working safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
• The gap between the bottom of the garage door and
the fl oor MUST NOT exceed 1/4" (6 mm). Otherwise,
the safety reversal system may NOT work properly.
• The fl oor or the garage door MUST be repaired to
eliminate the gap.
